The slewing bearing is the core component of the wind turbine and is widely used in the pitch and yaw systems of wind turbines. The pitch bearings are used to connect the wheel and the blades, and the yaw bearings are used to connect the tower and the unit. The wind power slewing bearing industry ha

The slewing ring is a rotary rolling or plain bearing. It usually supports heavy loads but slow or slow swinging loads, usually horizontal platforms. For example, a windward platform for a conventional crane, encoder or horizontal axis windmill. Slewing bearings have a thin cross section compared to other rolling bearings, typically having a diameter of 1 meter or more. The gear teeth are integrated with the inner race or the outer race to drive the platform relative to the base. Next, I will tell you the reasons and solutions for the inflexibility of the slewing ring bearing.

When optimized design selection of slewing bearing, the slewing gear is optimized by changing the modulus, it is necessary to comprehensively consider the two factors of gear tooth force and dynamic load fluctuation amplitude, and obtain a better dynamic load history within the gear bearing capacity

The single row crossed roller slewing bearings are arranged at right angles to each other at intervals between the inner and outer wheels. They can withstand loads from all directions (such as axial, thrust or momentum loads). Since the roller is in linear contact with the surface of the track, the bearing is less likely to be elastically deformed by the load. The single row crossed roller slewing bearing can be assembled in all directions of the spindle for easy use. It can withstand radial and axial loads at the same time, thus simplifying the structure of the device and reducing the weight of the mechanism.

With the gradual rise of new energy fields, the accompanying equipment manufacturers have sprung up. The slewing drives are derivatives of slewing bearings, which are used in different fields.

Slewing support is widely used in real industry. It is called "the joint of machine". It is an important transmission element for the machinery that needs relative rotation motion between two objects and bears axial force, radial force and overturning moment at the same time. With the rapid development of machinery industry, slewing bearings have been widely used in marine equipment, construction machinery, light industry machinery, metallurgical machinery, medical machinery, industrial robots, tunnel boring machines, rotary stage lights. Next, we briefly introduce the four point contact ball bearing and light slewing bearing, and briefly analyze the difference between them, hoping to help you better understand the four point contact ball bearing and light slewing bearing.
